If you spectate someone and they go to a different dimension, the spectator stays in the last location the player was

What I expected to happen was...:
The player spectating another player would continue to spectate the target in the correct dimension and coords

What actually happened was...:
The spectator stays in the same dimension at the last target's coords

Steps to Reproduce:
1. Get two players to join a game
2. Spectate one of the players
3. Have them go to a different dimension
